Title: Improvements in and relating to methods for the production of sulphanilic acid amidecompounds
IPC: C07D277/52
Filed: 1945-09-07
Abstract: Sulphanilic acid amides are obtained by treating bisulphite compounds of lower aliphatic mono-aldehydes with from 2 to 4 carbon atoms in the molecule with sulphanilic acid amides of the formula <FORM:0601709/IV(b)/1> where R is a heterocyclic radical such as pyridine, quinoline, isoquinoline, thiazole, thiodiazole or thiodiazine radical. Alternatively, the amide instead of being reacted with a previously formed bisulphite compound is reacted with the bisulphite and aldehyde.  Aldehydes mentioned are acetaldehyde, propionaldehyde, butyraldehyde and crotonaldehyde.  In examples: (1) an aqueous solution of sodium acetaldehyde bisulphite is added to 2-(p-amino-benzenesulphonamido)-thiazole to form 2-(p-(a -sulphoethyl)-aminobenzenesulphonamido)-thiazole; (2) propionaldehyde is added to an aqueous solution of sodium bisulphite followed by 2-(p-aminobenzenesulphonamido)-5-methyl-1 : 3 : 4-thiodiazole to form 2-(p-(a -sulphopropyl)-aminobenzenesulphonamido)-5-methyl-1 : 3 : 4-thiodiazole.  The Specification as open to inspection under Sect. 91 includes also the use of glyoxal as an aldehyde.  This subject-matter does not appear in the Specification as accepted.

Title: Helical wave guide
IPC: H01P3/13
Filed: 1976-06-08
Abstract: 1499947 Making wave-guides LES CABLES DE LYON SA 8 June 1976 [12 June 1975] 23627/76 Heading B3A [Also in Division H1] A helix waveguide, for, e.g. transmission of wave energy in the circular-electric mode comprises a conductive screen and a helix wound from a wire 14 coated with thermoplastic material, the turns of the helix being welded together by surface melting of the coating. The coating may consist of a polyolefine such as polyethylene, polypropylene or PTFE. As the helix is formed on a mandrel 11, heat is applied by means of a flame 17, hot gas, radiation or by high-frequency heating to effect fusion welding of adjacent turns. The mandrel may be cooled, e.g. by flowing water or by a heat pipe. The welding may be facilitated by application of a thin overlayer of thermoplastic substance. The helix is positioned in a screen which may consist of a seamed aluminium tube having an inside diameter slightly greater than the outside diameter of the helix. The tube is subsequently passed through a die to reduce the gap between the helix and the tube. A layer of heat-sealing material may be inserted between the helix and the tube at least near the ends of the tube. The tube may be protected from corrosion by means of a coating or wrapping, or by insertion into a flanged casing.
Patent GB-1470387-A (GB)
IPC: B60Q1/40
Filed: 1973-05-19
Abstract: 1470387 Road-vehicle direction-indicators LUCAS ELECTRICAL Ltd 25 April 1974 [19 May 1973] 23961/73 Heading G4Q A direction-indicator control circuit includes a manually operable switch 110 biased to its open position, an electromagnetic bi-stable latching mechanism which is operated when the switch is closed momentarily and serves to close a contact 106 coupling a flasher unit 107 to a lamp 108, and means operable upon completion of a turn for operating the latching mechanism to open the contact. In the embodiment a permanent magnet latching relay has a winding 103 which when energized changes over ("energized" positions) contacts 104, 105, 106 from the positions shown, the contacts being held over when the winding 103 is de-energized ; when the winding is energized again, in the reverse current direction, the contacts are moved back to the positions shown ("normal" positions). Automatic release after completion of turn.- Steering column 116 includes a permanent magnet 117. Assuming a left-hand turn, reed switches 118, 119 are actuated as follows:- switch 118 closes, then switch 119 closes with switch 118 still closed, then switch 118 opens but switch 119 remains closed and thereafter switches 118, 119 both open; on return of the steering wheel the opposite sequence occurs. The overall action of a bi-stable transistor circuit 124, 125 is to ensure that transistors 131, 132 remain off until switch 118 closes on return movement of the steering wheel whence the lower end of winding 103 is connected through transistor 132 to earth and contacts 104, 105, 106 return to their normal positions. Similar arrangements are made for a right-hand turn, including a manual switch 110a and reed switches 118a, 119a. Cancellation of flashing is effected by pressing switch 110 again and is useful when changing lane, steering wheel movement not then being sufficient to close switches 118, 119. Diodes 120, 120a stop flasher unit operation if the "opposite" switch is closed. Tell-tale 109 is included.
